It's funny how the trend in cell phones use to be to keep making them as small as possible, then smartphones go mainstream and now it's all about going as large as you can go. We have the 5.5 Note 2, we have the upcoming Hauwei mate at 6.1, and more rumors beyond that. I started with Galaxy S1 (4), then a Samsung Charge(4.3), and currently have a Gnex(4.6). The Gnex screen is actually a little too large for one handed usage for me because I have small hands unfortunately, so I don't think I would want to go larger than 4.7. So anything between 4.5 & 4.7 I think I'll be happy with.
